A Doe will leave her fawn, regularly, this time of year, and may travel 1/4-1/2 mile, but usually only a few hundred yards from her fawn(s). She will only come near it to feed it - 2-3 times a day, after the first week or two. It is safer for her NOT to have a lot of contact with her fawn(s) for the 1st 2 months. Predators intent on a fawn for a meal, follow the mothers, since its difficult to locate hidden fawns.

It sounds very likely the doe you saw was the mother (or another mother you may not have seen the fawn to). But most likely the mother of the fawn. If the fawn is a doe, she may become almost tame growing up around the house (probably like her mother). If the fawn is male, it' ll leave for 5-20 miles away likely next spring or fall.

Take some pictures if you can, differnent deer are easily distinguished by markings if you have good photos.
